As a average joe shooter, I found that bowling pin shoots are great training aids, as you get immediate reaction: aka pin slide back away and drops off table or flops down and SPINS around from bad placement. Also for loading for next table, I keep eyes on the table and feel the speedloader / mag into the sidearm in use.

If a pistol malfunction occurs keep eyes on table and do the Jeff Cooper slap the mag into frame and rack slide back and continue firing, if not cleared then you are DONE!

If you need a sixth (J- frame)/seventh shot form your revolver, you're DONE!
